Wolbachia are maternally inherited bacterial endosymbionts that found in different arthropods. It is now well known that they induce reproductive phenotypic manipulations like feminization, thelytokous parthenogenesis, male killing and cytoplasmic incompatability in their arthropod hosts. Although diverse insects are infected with Wolbachia bacteria and generally for their insect hosts, it is regarded as facultative/parasitic endosymbiont bacteria. The Wolbachia strain, designated as wCle associated with the bedbug Cimex lectularius was shown to be vital for the growth of host’s and reproduction via provisioning of B vitamins. Previously the infection of endosymbiotic Wolbachia bacteria has been shown to the colonies of the human bed bug, Cimex lectularius L. (Heteroptera: Cimicidae) cultured in the laboratory, but no information exists regarding the infection status in natural populations in India. We assayed Cimex lectularius populations from different areas of Vidarbha region (Akola, Amravati, Chandrapur, Nagpur), Maharashtra, India for Wolbachia infection. Detection was done by the polymerase chain reaction (PCR). Wolbachia infections were prevalent in all populations assayed (75–100%). Higher rate of Wolbachia infections were found in bedbugs of Vidarbha region of India, which indicates importance of this association. The characterization of these Wolbachia strains provides a deeper approach into this interaction, which is essential for further studies. The potential utility of Wolbachia for another bed bug control strategies is discussed.

The present study was carried out in the West region of Chhindwara district of Madhya Pradesh (India) to document the diversity and utility of avian fauna. Many of the wild life species are gradually vanishing from our forest. The biological imbalance created due to disappearance of particular species which have put may problem. The national forest policy 1952 has laid special emphasis on preservation of wild animals. The inhabitants of the region are dependent up to a large extent on wild resources for their remedial needs. The region is rich in avifaunal diversity having 124 species belonging to 17 orders and 46 families. This study will be helpful in developing a comprehensive data base on the faunal resources to strengthen the care system in the area and in conserving the avifaunal resources for the prosperity of the region.

Oxygenated peptones and Vermiwash are commonly used in organic farming practices. In the present investigation, experiments were carried out to study the influence of Gibberellic acid (50 ppm), Oxygenated peptone (1% aqueous) and Vermiwash (20%) on fenugreek (Trigonella foenum-graecum L.) var. early bunching during seed germination by using petri-plate method. Distilled water was considered as control. Oxygenated peptone and Vermiwash showed promontory effect on germination percentage. All three treatments stimulated vigour index and also showed enhancement in fresh and dry weights of root and shoot. Oxygenated peptone and Vermiwash showed supremacy in root length while GA treatment remarkably enhanced shoot length. Oxygenated peptone, Vermiwash and GA treatments showed significant improvement in the amount of total carbohydrates, soluble proteins and activities of enzymes like amylase, protease and catalase. The study revealed that Vermiwash, Oxygenated peptone and GA improve the process of germination with positive alteration in biochemical aspects.

Water management in general takes account of biodiversity and conservation aspects, but further some protective measures are needed. Cost of water management directly or indirectly influences the aquatic ecosystem. Biotic and abiotic factors are both independent and interdependent resources. Multispecies communities like plankton, fishes and macrophytes are bioresources which are essential for the stabilization of ecosystem. Bioindicators and bioresources are both responsible to maintain the food chain of pond ecosystem. Species composition and biomass distribution are important for affecting the transfer of energy in food chain of pond. Phytoplankton represents the base of primary producer in aquatic ecosystem and plays a major role in the global cycling of carbon, nitrogen, phosphorous and other elements; and by this they help in regulation of the earth’s climate. Bioresources are the natural bioindicators of pollution in the water body. Bioindicators are anthropogenically induced which affects biomolecules, their biochemical and physiological parameters that are casually linked to the different levels of biological organisation. Sometimes the reason behind loss of biodiversity is due to competition between bioresources in a limited space. Present investigation is an attempt to study and understand the basic status in hydrobiology and productivity possibility of reservoir.

One of the grand tasks of current taxonomy is to prepare a checklist of plants of the globe. This work is largely based on collecting information from regional floras and databases. Till this date, the progress is relatively slow, as the number of common names, synonyms, poorly resolved aggregates is high. For this purpose regional flora, checklists and databases with reliable taxonomy and complete coverage of critically examined data are required. The majority of novelties come from the tropics; but certain areas remain poorly explored as well, and numerous species in these areas still await recognition. In the present work, the studied area is Vidyabharati Mahavidyalaya campus which is situated in the prime location of the Amravati city. Amravati is a district in the state of Maharashtra with its district headquarters situated at 20˚55ˊ33̎ N and 77˚ 45ˊ53̎ E. The district is situated at 343m (1,125ft.) asl. The present study deals with the floristic diversity of campus in the former sense, i.e., the number of individual species in the area. The present paper attempts to highlight the diversity of vast plant resources of the campus in a conservation perspective. A total of 91 species of flowering plants are documented in which 43 were herbs, 25 shrubs, and 24 angiospermic trees distributed in 22, 13, and 12 families respectively.

Fabaceae is the largest family, represented by total 116 species in the Melghat Tiger Reserve. Present paper deals with the addition of 02 new reports of Fabacae members namely, Flemingia macrophylla (Willd.) O. Ktze. ex Merr. and Paracalyx scariosus (Roxb.) Ali, to the flora of Melghat Tiger Reserve. Correct and updated citation, local name, a short description, along with distribution, is provided for future field work.
